No, it is a code object which you send to the calculator, store to a variable and run from there. The reason I didn't put it into library is because I use some self-modifying code to fixup lots of address at startup, so I can use absolute addressing no matter where the interpreter has been loaded into memory. I am not sure it would work correctly with libraries.

Quote:Is it coded in native code (with assembly or hpgcc) or sysrpl?

The good old pure machine language, with the exception of some SysRPL code during initialization
